PT'IING-OUT MACHINE Specieation of Letters Patent.

Patented Aug. 17', 1909.

Application inea my 2s, 1904. serial No. 218,447.

To all whom it may concern:

Ee it known that I, FRANKLIN J. nnirrns, a citizen of the United States,residing at W'oburn, in the county of Essex, State of Massachusetts,have invented a certain new and useful Improvement in Putting-OutMachines, of which the following is a specification, reference being hadtherein to the accompanying drawings.

rThis invention relates to a machine for working hides, skins andleather, and is especially adapted to perform the operations of puttingout, unhairing, setting etc.

Heretofore, it has been the custom to work hides by means of such amachine as is shown in my Patent No.716,1411 dated December 8, 1903, butconsiderable difficulty has always been experienced in successfullytreating the part of the skin which lies over the end of the operatingtable, shown in that and other patents. The portion of the skin whichlies over the end of the operating table is that portion which liesalong the vback bone of the animal.

My present invention has for its object to `provide a machine whichshall work the portion of the skin which comes over the edge of thetable of the ordinary putting out machine independent of the machinewhich works the remainder and major portion of the hide or skin. rThisoperation may beperformed upon the machine embodying my presentinvention either before or after the remainder of the skin is worked,but I have found it more satisfactory to perform this operation beforethe rest of the hide is worked, because if the portion of the hide alongthe back bone is worked after the remainder of the hide, the water etc.in the back portion is driven again into the sides of the hide and apoorly finished hide is produced. On the other hand if the back of thehide is worked first in my preliminary machine and the hide is afterwardworked in an ordinary serial table machine, the water etc. which isworked away from the end of the table on both' sides is completelyremoved from the hide by the second operation.

Referring to the drawings-Figure 1 is a side elevation of a machineembodying my invention, certain portions being shown in section forgreater clearness. Fig. 2 is a front elevation and Fig. 3, a detail tobe referred to.

Having reference to the drawings, 1 is the framework of the machine andis of any convenient form adapted to support the various operatingmembers. An operating roll or tool 2 composed of a series of helicalblades of the well known form is supported in suitable bearings 11 and12 on the frame 1 and is driven bya belt, not necessary to be shown,running upon the pulley 3 which is fast to the end of the axle L1 of theoperating roll.

The skin or hide to be worked is thrown over a pad 5 having a circularcontour on the side next the operating roll in order that the properportion of the skin may engage the surface of the operating tool 2, theamount of the skin which engages with the operating tool beingdetermined by the shape and size of this pad 5. The pad 5 is carried bya pair of swinging supports 6 and 7 which are pivoted at their lowerends to the frame of the machine. By the movement of these swingingsupports 6 and 7, the skin upon the pad 5 is caused to engage thesurface of the operating tool 2. The pad 5 is made of wood with ayielding covering of leather or other similar material in the mannercommon in such cases, and is provided with pivots 51. at each end uponwhich the pad may turn in relation to its supports 6 and 7. Projectingfrom each end of the pad 5 is a stop 52 which projects into a slot 53 inthe side of the support. By this means the amount of swing of the pad 5about the pivot 51 is limited, so that the pad cannot turn over but canstill adapt itsllf slightly to the position of the operating ro 2.

To move the pad 5 in and out of contact with the operating tool, Iprovide the following mechanism. A shaft 3 which will be called thelower countershaft is located in suitable bearings S1 on the frame 1 ofthe machine and is driven by means of a chain 9 and a pair of sprocketwheels 101 and 102 located upon the shaft 4 of the operating tool and onthe lower countershaft S respectively. On this countershaft 3 is placeda frictionclutch 121. In the lower part of the machine is a treadleshaft 13 upon which are a treadle 131 and a weight 139 which tends tokeep the treadle in its raised position. A fork or ring 132 for theclutch 121 is attached to the upper end of an arm 133 fast to thetreadle shaft 13, and two pointed pins 131.'c and 135 are screwedintosuitable holes in the sides of this ring 132. These pins 134 and 135engage the cone 136, which in turn engages and operates the lever 122 ofthe fricof clutch may be used.

tion clutch 12. It is unnecessary to describe the friction clutch 12, asits construction iswell known and any convenient form The upper end ofthe arm 133 which carries the fork or ring 132 also carries a roller 137which is free to turn about the spindle 133. The object of this roller137 will be hereinafter' more fully described.

A second or upper countershaft 14 is located above the lowercountershaft 3 and carries thereon a large gear 15 which meshes with andis driven by the small gear 15 on the lower countershaft 3. On each endoic this upper countershaft 14 is located a crank 161 operating a pairof connecting rods 17 which move the pad 5 toward and away from theoperating roll 2 with each revolution of the upper countershaft 14.

Upon the upper countershat 14 is a stopdisk 141 having a raised rim 142within which are two oppositely disposed depres sions or notches 143,and 144. When the treadle 131 is depressed the roller 137, previ.- ouslyreferred to, which is carried by the upper end of the fork or ring 132,is lifted from the depression 143 in which it is shown as resting, andas the stop-disk 141 turns with the hopper counter-shaft 14, the roller137 rolls around on the edge of the rim 142 until it drops into thesecond depression 144, by reason of the wei ht 139 against the action ofwhich the tread e 131 is depressed. lli/Then the roller drops intoeither of the depressions 143 and 144, the cone 136 releases the clutchlever 122, and the movement of the gear 15 and the pad 5 ceases. By thisarrangement of parts, it will be seen that the machine stops when thepad 5 has reached the limit of its movement away from the operating roll2, giving the operator an opportunity to take oil' one hide and put onanother before starting the machine again. This stop disk also stops themachine when the hide is in contact with the operating roll 2 and theparts remain in this position until the operator thinks that the hide orskin is suiliciently worked, and again depresses the treadle. Theabove-described parts of the machine stop twice for every revolution ofthe stopdisk 141. Of course it is to be understood that the operatingroll rotates continuously and independently of the remainder of themachine.

To prevent the skin or hide from slipping on the pad 5 during theworking a clamp is provided. (See more particularly Fig. 3.) At each endof the frame of the machine are placed guides 18 in which slides a clampbar 19 which is held in engagement with the skin or hide by means of thespring 22. This clamp bar is provided with a blunt or rounded edge 191for engagement with the skin, and holds the skin i'irmly between thisedge and the upper edge of the pad 5. The

pressure ofthe clamp bar 19 is adjustable by means oil the screw 23which passes through the ends oi the guides 13 and is held in place by acheck nut 24. W hen the movable pad 5 is brought into engagement withthe clamp bar 19, the clamp bar is moved back until the surface of theskin upon the pad 5 is brought into contact with the operating roll 2.An upper clamp bar 192 is fastened to the clamp bar 19 by a bolt 193 andprojects over the top ol" the pad 5 when it is in working position, thusholding the hide at a second point and making it certain that the hidedoes not slip during the working operation.

In order that the skin may be pressed against the operating roll withthe right amount of pressure some adjusting means between the crank 161and pad 5 is necessary. To accomplish this l provide the connecting rod17 with two end pieces 25 and 26, having screw-threaded holes thereinfor the reception of the ends of the connecting rods 17 which areprovided with right and left hand screw-threads. By turning theconnecting rod 17, the two end pieces 25 and 26 may be drawn nearertogether or spread farther apart as is required. Check nuts 251, 261,are provided to keep the jarring oi the mae chine from loosening theconnecting rod 17.

When the machine is in use, the operator throws a skin or hide over thepad 5 so that the portion of the skin or hide which was over the backbone of the animal comes over the pad 5 between its upper and loweredges. He thon presses down the treadle 131, which causes the clutch 121to operate and starts the rotation ot the gear 15, thus bringing themovable pad 5 into engagement with the operating tool 2, while the clampholds the hide firmly against the pad 5. When the stopdisk 141 hascompleted half a revolution, the roller 137 drops into one ot thedepressions in the stop disk and causes the gear 15 to cease itsrotation, thus holding the hide or skin in Contact with the operatingroll until the operator again depresses the treadle. The pad 5 thenmoves back out of the way of the operating tool, so that the operatormay remove the hide and repeat the operation.
